UNH'EEE STATES PATEN'E PUSH BROOM OR BRUSH.

Application filed January 21', 1922. Serial No. 530,771.

To all whom it may concern:

Be it known that I, HARRY D. Nnrr, a citizen of the United States, and a resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Push Brooms or Brushes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My present invention relates to brooms and brushes, and more particularly tobrooms and brushes of the so-called push type.

In my Patent No. 1,411,221, dated March 28, 1922, I have described and claimed an improved form of broom or brush unit adapted to be inserted in a hollow head or holder, this unit being composed essentially of a bunch of fibres, bristles or the like, clamped at one end by an encircling band that is given a shape to fit snugly in the holder and assist in retaining the unit, or a plurality of units, in position in'such holder. In this my present invention, I have dopted a unit having the same characteristics as the above referred to unit, as regards shape of the band, but have improved thereon by making a double ended unit, by making the clasping band in the shape of a substantially double cone, with the apex at the center, the bundle of fibres, bristles or the like being clasped at a point intermediate their ends to present two sweeping or brushing surfaces: To utilize this improved form of unit, I have devised an eflicient and economical form of holder provided with a plurality of the individual pockets or sockets for such units, this ho der being made in two parts and held together in any suitable manner.

The principal object of my invention therefore, is an improved broom or brush of the push type.

Another object is an improved form of holder for a broom or brush of thi type.

Still another object is an improved form of broom: or brush unit for such type of broom or brush.

Other objects and novel features of the construction and arrangement of parts will appear as the description of the invention progresses.

In the accompanying drawings illustrating the preferred embodiment of my invention,

Fig. 1 is a front elevation;

Fig. 2 is a plan view, and. Fig. 3 is. a sectional side elevation taken on the line 33 of Fig. 1.

Referring to the drawings, 10 designates a head having a socket 11 formed, integral therewith and into which fits a handle 12 of any suitable length. Formed in the front face of this head 10 are a plurality of depressions, the inner surfaces of which: are bevelled, a shown at 13'. Cooperating with this head 10 is a second head 14 provided with studs 15 which project through the head 10 and are provided with wing nuts 16 for securing the heads 10 and 14 together. On the inner face of thehead 14 are aplurality of depressions, equal in number to the number of depressions in the head 10, the inner surfaces of these depressions being bevelled, as shown at 17, the depressions in the heads 10 and 14 forming together pockets or sockets 18 that are substantially double cone shaped in cross section, as clearly shown in Fig. 3 and the entire assembly forming a holder.

The broom or brush units each comprise a bunch of fibres, bristles or the like, 19, firmly held together by a: clasping band 20, that, in the finished article, double cone shaped in end elevation, and fits snugly in the pockets or socket-s 18 formed in and by the heads 10 and 14. When the clasping band 20 is placed in position on the bunch of fibres, bristles or the like 19, the cross sectional area of such bunch is reduced at the clasping point allowing the ends'to flare outwardly, as indicated at 21.

The method of assembling and operating my improved broom or brush will be apparent from an inspection of the drawings. The wing nuts 16 are backed ofl' from the studs 15, the head 14 separated from the head 10, a plurality of bunches placed in the depressions in the head 10, the head 14 replaced in position, and the wing nuts 16 employed to bring the heads 10 and 14 into close association, this operation firmly clasping the units in position in the holder. As so assembled, the broom or brush is ready for service, and the lower ends of said is substantially ioo bunches, as shown in Figs. 1 and 3, will wear bunches may be turned end for end thus bringing the upper ends, as shown in Figs. 1 and 3, into position for use.

These bunches are capable of being manufactured and sold for a reasonable sum, and have twice the Wearing surface and length of any ordinary broom or brush of this type as ordinarily constructed. Further, the holder is practically indestructible, and may be used indefinitely, the only expense for upkeep of the groom or brush being for new units.

While I have shown and described the preferred embodiment of my invention somewhat in detail, it is to be understood that I may vary the size, shape and arrangement of parts comprisingmy device within wide limits without departing from the spirit of the invention.

Having thus described my invention, what I claim as new, is:

An improved push broom or brush comprising, a head provided with a plurality of depressions in one face thereof, a second head provided with a plurality of depressions in one face thereof and equal in nuin.

her to the number of depressions in said first head, said depressions cooperating with each other to form a plurality ofsocket-s, the surfaces of said depressions being bevelled and cooperating to give said sockets a double cone shape in cross section, double end broom or brush units fitting into said sockets, and means for holding the heads together.

In testimony whereof, I have signed my name to this specification.

HARRY D. NEFF.
